Demand for Nonprovisioning Ecosystem Services as a Driver of Change in the Canadian Boreal Zone
Resource
The Canadian boreal zone provides ecosystem services from local to global scales. Either directly or indirectly, demands for these services have and will continue to serve as drivers of change in the...
Demographic Declines Over Time and Variable Responses of Breeding Bird Populations to Human Footprint in the Athabasca Oil Sands Region, Alberta, Canada
Resource
Habitat loss and disturbance from industrial resource development may be contributing to declines in boreal bird populations. We applied hierarchical multi-species models to data from 31 bird species...
Dendroecology and Genomics in Support of Forest Carbon Capture
Resource
Globally, forests play a significant natural role, as they absorb and sequestrate carbon that would otherwise end up in the atmosphere. This carbon sequestration mitigates the phenomenon commonly...
Denitrification Potential of Surface Soils of Constructed Wetlands in Newtown Creek, an Urban Superfund Site
Resource
Denitrification, the anaerobic microbial conversion of nitrate (NO 3 −), a common water pollutant, to nitrogen (N) gases, is often high in the soil of natural wetlands. In areas where natural wetlands...
Densified Fluid Fine Tails and Oil Sands Process Water - an Extension of the 2017 Study - Final Report
Resource
A mesocosm study was undertaken to support the development of end pit lake technology. The mesocosms were exposed to OSPW (Oil Sands Process affected Water) and dFFT (densified Fluid Fine Tails).
Densified Fluid Fine Tails and Oil Sands Process Water: A Screening Study - Final Report - Study Plan Number: MES-2017-1
Resource
This study utilized mesocosms to investigate the effects of oil sands process water (OSPW) and densified fluid fine tails (dFFT) on aquatic ecosystems to support development of end pit lake technology
Deposition of Sulphur and its Influence on Soils in the AOSERP Study Area
Resource
Several field investigations were carried out to determine the amounts of sulphur deposited in rain, in rain washing off trees, and by direct absorption of SO2 by soil
Design and Performance Enhancement of Mine Drainage Settling Ponds in Alberta
Resource
There has been increasing concern in recent years regarding the environmental impact of sediment laden runoffs discharged from land disturbing activities in Alberta. Settling ponds represent the most...
Design of an Oil Waste Land Treatment Facility for the Cold Lake Production Project
Resource
Esso Resources Canada Ltd (Esso) operates an oil sands production project at Cold Lake, Alberta that produces approximately 14,000 m3/day of bitumen for the world market. On December 8, 1988 a failure...
Desktop Planning: Mapping Your Way
Resource
This document is part of the 360 tours project Toolkit developed by Canada's Oil Sands Innovation Alliance (COSIA) led by Cenovus Energy Inc., in collaboration with Natural Resources Canada. The...
Detection of an Invisible Foe: Annosus Root and Butt Rot
Resource
Annosus root and butt rot was first reported in Quebec in 1989. The causal fungus enters a pine stand by colonizing the surface of freshly cut stumps. The disease spreads through contact between the...
Detection of Coniferous Seedlings in UAV Imagery
Resource
Rapid assessment of forest regeneration using unmanned aerial vehicles (UAVs) is likely to decrease the cost of establishment surveys in a variety of resource industries. This research tests the...
Developing a Reclamation Costing Framework for the Athabasca Oil Sands
Resource
The Athabasca oil sands are a significant component of the economy in Alberta. However, they also represent a large environmental risk. At the end of mining operations, companies are expected to begin...
Developing Allometric Equations for Estimating Shrub Biomass in a Boreal Fen
Resource
This study develops allometric equations for three dominant genera found in boreal fens: Alnus spp. (alder), Salix spp. (willow) and Betula pumila (bog birch).
Developing Monitoring Protocols for Aquatic Ecosystems in Forested Regions of Alberta
Resource
This report is part of a larger endeavor to develop a monitoring program capable of detecting changes in the biological diversity of Alberta’s forested region.
Development and Application of Soil Quality Criteria for Alberta's Resource Extraction Industries
Resource
Soil quality criteria for Alberta's resource extraction industries were prepared by the Soil Quality Criteria Subcommittee of the Alberta Soils Advisory Committee. The document produced was intended...
Development of a Climate-Sensitive Structural Stand Density Management Model for Red Pine
Resource
The primary goal of this study was to develop a climate-sensitive modular-based structural stand density management model for red pine plantations situated within central North America. For a given...
